10 Q PROBABILITY PRACTICE

Front

What is the probability of drawing a green odd number from a set of colored numbers?

Back

P(green, odd) = 0

Front

What is the probability of drawing a blue item from a set of items?

Back

P(blue, X) = \frac{1}{15}

Front

What is the probability of not drawing a red item from a set of items?

Back

P(not red, X) = \frac{1}{5}

Front

What is the probability of drawing a white item numbered 4?

Back

P(white, 4) = \frac{1}{24}

Front

What is the probability of drawing a black item numbered 2?

Back

P(black, 2) = \frac{1}{12}

Front

Define probability in the context of drawing items from a set.

Back

Probability is the measure of the likelihood that an event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is the formula for calculating the probability of an event?

Back

P(E) = \frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ outcomes}.

Front

If there are 8 total items and 2 are blue, what is the probability of drawing a blue item?

Back

P(blue) = \frac{2}{8} = \frac{1}{4}.

Front

What does it mean if the probability of an event is 0?

Back

It means that the event cannot occur.

Front

What does it mean if the probability of an event is 1?

Back

It means that the event is certain to occur.
